perfSONAR User Q&A and Other Discussion

[Jason Zurawski <>]

Hi Lixin;

In looking at the logs, we don't see anything out of the ordinary, the 
'duplicate' message you see is actually just unfortunate wording on our part 
- it means 'renew' the registration instead of making a new one.  Since you 
noted you changed DNS/IP, it may be an issue of a stake cache.  Try the 
following steps:

> sudo /etc/init.d/ls_registration_daemon stop
> /var/lib/perfsonar/ls_registration_daemon/lsKey.db
> sudo /etc/init.d/ls_registration_daemon start


This will stop the service, delete the local db, and then start it all over.  
After a couple of hours the information should show up, or at a minimum the 
logs will let us know if there is something else locally bad that is going 
on.  

As an aside, it appears that your NTP is not configured, some of the tools 
may not work until that is fixed.  You may want to run the NTP configuration 
script again. 

Thanks;

-jason
